Problems solved by technology
[0002] Due to the existence of random errors, the actual outer trajectory of the guided ammunition will always deviate from the planned outer trajectory. At the same time, due to the limitation of technical conditions, the actual outer trajectory cannot be accurately predicted, which will affect the correction effect of the outer trajectory, and then affect its hit probability.

The invention discloses a simulation platform for correcting of a closed loop of an outer trajectory of guided munition. An outer trajectory correction mechanical arm performs outer ballistic flight according to a pseudo-planning trajectory control guided munition model; a real-time analysis module is used for carrying out smoothing filtering or kalman filtering on three-axis position data, three-axis speed data and three-axis acceleration data, and the real-time triaxial position information of the guided munition model in the flight process of the outer trajectory is obtained, the real-timethree-axis speed information and the real-time three-axis acceleration information; a decision-making module is used for obtaining a mechanical arm control instruction for correcting the three-axis position, the speed and the acceleration; and the outer trajectory correction mechanical arm is used for simulating the three-axis position, and the triaxial speed and the three-axis acceleration correction of the guided munition model in the flight process of the outer trajectory. According to the simulation platform, accurate closed-loop simulation of outer trajectory correction of the guided munition is realized.
Description
Technical field [0001] The invention relates to the field of guided munitions and the technical field of information physical systems, and specifically refers to a closed-loop correction simulation platform and simulation method for the outer ballistics of guided munitions. Background technique [0002] Due to the existence of random errors, the actual exterior trajectory of guided munitions will always deviate from the planned exterior trajectory. At the same time, due to technical constraints, the actual exterior trajectory cannot be accurately predicted, which affects the correction effect of the exterior trajectory and affects its hit probability. Therefore, how to accurately obtain the outer trajectory of guided munitions to ensure the corrective effect of the outer trajectory is a key scientific issue for guided munitions to improve the hit probability. Summary of the invention [0003] The present invention provides a closed-loop correction simulation platform and simulatio...
